    Comments: MCC called and asked for ABU and BANU, and then told me it was wrong (0.96 and 2.22h). Added it all up by hand and go the same result. It seems that MCC believes they were indeed sending us beam that was in fact counted as Beam Not Available. Perhaps this is because we are running at 0.5uA and the beam-accounting program does not count this amount of current (<1uA) as being "available". They will include this on their "Requires attention" list.
